Find out what the hardware that preconfigured computer has. Whether it has
an Intel processor or some other. Then see if Redhat has Linux for that
platform. www.redhat.com If it has then you definitely can install RedHat
Linux on that m/c.

You'll have to read the config file into the current version of
the configurator, check the options, and write it out again.
New symbols have been introduced between 2.2.5 and 2.2.14.

A lot of work has gone into making the transition from libc5 to libc6
as painless as possible, although admittedly no one that I know of
still works on improving that support.

The easiest way to accomplish this is to run
# make oldconfig
followed by
# make dep ; make clean
before you do the real make of your new kernel

You can wrap the program up in a shell under nohup in that case, such
as:
nohup tcsh -c 'myprog >&! /tmp/myprog.log' &
That should isolate any tty operation from impacting on the current
screen, unless it's doing something really wierd (like Angband with a
bot player might not work this way!).

A file is nearly everything but some peripherical need more speed like
video card, so you have to find an other system !
I know all of this but if you are juste a secretary you absolutely
nevermind about this. You just want to refind every file you have
written. The system isn't your problem at all. But it's the same problem
for common people at home. They want to use internet, write letter,
maybe play networks game or have a little network with a server
connected to internet. In the ideal word, they just need to plug the
cable and some application will make it fine. It isn't because windows
make it very bad, that nobody can make it clean.
Or you think that linux arn't for common people ?

When you look the directory of an application you can see many other
files than the executable file and many other directories, sometimes
it's for configuration, but more often it's just internal thing. And
it isn't usefull to see all that stuff.
I know you can sleep well even you see that directory but it's just the
concept of application that i want to clarify. If 'wc' use 'wc_foo'
during a run, you don't need to see it in your file system.

I'm not sur. What could you do, if you have install some programs
without package manager, and some others with rpm. If you look what
is install with rpm you can't easly know if a pakage is need by a
program that you have installed without rpm. And some times you want
to delete all program that you don't need but it's hard to know
exactly what you must keep.

Maybe i'm a little lazy but i didn't remenber all what i have doing
with my system !
Sorry, but each package manager use the informations given by the file
it self. Under windows, if every programs could have a clean remove
option, our system directory will not explode. And you have to trust
the people who create the rpm pakage.

Yes and you have to make ./configure and ./makefile and to pray for
everything would be fine. In the opposiste, you have to be an expert
or take many hours to earn how to solve the problem.
My imaginary system will have enough information to manage it-self

Maybe this last line could explain yours positions : This system is
fine and if you want to try to make it easier it would seems like
windows and it's bad.
My position is to think for beginer or for user who absolutely
nevermind about how it's system work. I want that everything could be
easly installed (maybe the only thing that Wxx does well) and that is
application should work fine.
No need to know how a network is see in the system or how the
processes communicate.
If you prefer my idea his to hide the main part of file system which
is see thought filter. You could manage that filter and this filter
can help you to manage your file. And that filter could be used to
filter what is see by some applications,...

Try downloading the pcmcia modules and building from source with
a running kernel. You might also check the source to get the URL
for Donald Becker's home page - there are lots of useful
diagnostic utilities there. The pcmcia development team (consisting
foremost of David Hinds) has a mailing list at sourceforge, so
you might check the mailing list to see if there is anything special
about your card.
Oh yeah, start by reading the PCMCIA-HOWTO.

Subject: Problem with SIGALRM and rad() from a pipe
Date: Tue, 29 Feb 2000 16:34:39 -0000
Hi All,
I've an interesting problem with the following piece of code under Linux.
What I expect when the alarm expires is that the read from the pipe "pipe1"
terminates - this is what
happens under other version of Unix - but under Linux the read continues.
The effect is that
the program appears to have hung.
Any ideas on this ?
#include <stdio.h>
#include <signal.h> /* signal header */
#include <unistd.h>
#include <fcntl.h>
#include <sys/stat.h>
#include <sys/types.h>
void Salarm(sig)
int sig;
{
signal (SIGALRM, SIG_IGN);
fprintf(stderr, "alarm came\n");
}
main()
{
int Salarm_signal = 0;
int fp;
signal (SIGALRM, Salarm);
alarm ((unsigned)5);
fprintf(stderr, "before open\n");
fp = open("pipe1", O_RDONLY);
fprintf(stderr, "after open\n");
fflush(stderr);

If you have purchased the CDs, then the source code of everything is on
the second CD. The linux kernel source code can be installed through the
rpms kernel-souce and kernel-headers (they should be on the first disk)
or through the source rpm kernel-whatever on the second disk.

And, in fact, I *can* do my FP work in user space; I have a shared library
which is used for all access to the driver environment; I can just pass
register sets back and forth between the driver and the library.
I just didn't like the taste of that; the low-level physical driver is the
code which actually needs to manipulate the registers; it seems improper,
somehow, to copy my whole register map into a buffer, pass it up to the
library, let it modify the map and return it to me... and what if I (the
driver) want to revise my registers when I'm *not* being called by a
user-level process?? I can't call the library on my own...
So I have a situation where I have all these registers in this hardware, I'm
supposedly responsible for making everything work properly, but I can't
actually configure things myself - I have to wait for "social services"
(i.e., some user-level process, via my library) to deign to drop by and
think for me...
However, If that's what I have to do, I'll have to live with it...
(Hey, if people can anthropomorphize their car, I can do so with my driver,
eh??)
